摘要：

A new experimental procedure was proposed based on genetic algorithm for analyzing exterior wall surface heat transfer process and deducing exterior wall surface heat transfer coefficient under actual conditions. Tests were carried out under a wide range of conditions, and the heat transfer coefficient was found vary from 14.315 to 24.412 W/m(2) K while wind speed ranged from 1.04 to 7.36 m/s, and correlation was obtained in terms of the wind speed. Tests revealed that the commonly used correlation for predicting the heat transfer coefficient was overestimated, especially at high wind speeds. (C) 2003 Elsevier Ltd. All rights reserved.
